'Application md December To 'all whom it may concern:

Be it known vthat l, WILLIAM CnYDn LEONARD, a Acitizen of the United States, -residinoat Lewiston, in vNez Perce County and "tate 'of Idal1o,`have invented certain new vand useful ImprovementsV in "Disk Wheels,'of which the following isa specification. p

The kvpresent Y invention relates to improvements in disk `'wheels of the type used in connection 'with lautomobiles, trucks, fand other 'automotive vehicles. The invention involves the use of ydouble disks of pressed steel which are t'co'nbined "andarranged lat the rim and hub portions in fsuch manner asto provide 'ars'tronjg-ai'id well' braced and durable structure, which structure is vcoinposed of apractical minimum number-of p'artsrende'ring its construction very simple but effective. 'In itsassembly the parts-of the wheel may with 1facility and 1`convenience be lirnily and 'securely vfixed 'against displacement and the wheelstructure placed under thefreqi'lired tension frdurability and strength. n

The invention consists in lcertain novel combinationsfand arrangements of parts'fat the hub and rim iportions of the Wvlieel fas will hereinafter be morefully described and claimed. Y

`'In the "accompanying drawings fI have illustrated one ycomplete example fof ythe physical 'embodiment of my invention wherein the parts are Icombined and -arranged in accordance cwith the bestmode I have thus far devised forfthe'pr'actical =ap plication of tl1e:p1incples'ofn1y invention.

dished or of -concavo-conven formation as indicated in Figg. vNear lthe rimfportion of the wheel these sections are broughttogetherto form a-lat annular `contacting area designated fals' to formfa double-thick vertically disposed .ring within the `irm which latter i's designated 'as whole by the.' numeral 4. The rinris ifashioned Offintegral :parts of the two'disksorsections l and 2which are madezto overlap A'and y:torni an eflicient supporting structure iforithe u'sual pneumatic tire or other-type of tire.

Iii-Figure l it will `.be yseenthatithe disk section 'l A at yits periphery is :provided `with a lateral, lannular rimfflangewhich projects outwardly 'from the `rbody of the `Sectionyandaat Gthis flange is bent upon itself, with a return bend, 'to 'formthe l tire-retaininxg flange yat the louter isidefof ythe wheel. The -tire-retaining flange terminates in an angular flange 7 -which `lies` close against the inner face ofthelateral liange with/its inner `edge adjacent 'to fthe ydouble 4wall 3 ofl the wheel.

A complementary rim-formation is. fashioned at theperipheryof the-disk 2, which isprovid'e'd withfa lateral vrim-flange Sap'rojected 'inthe opposite vdirection fifromi'fla'nge 5. The-flaring tireeilange 9 is formedlby doubling and folding vthe metal @and l'this flange terminates in Ythe 'exterior annular flange 10 whichfeXtendsacross the rim to the complementary tire-angeV .6.

These hanged partsforming the rim structure 4; provide an annularchannel 4for vthe reception land retention 'of lthe standard typesof tires, Vthe vstructure being "strong and well braced andi capable of supporting the. required 7loads.

The two sections of t-he disk wheel yare interlocked and vvare Yrelatively .i movable for assembly and for dismounting, and-for this purpose fa series of'bolts 11 arefspacedfat regularintervals around the fiat ring 8, 'ea-'ch bolt lextending transversely through the sections yand i provided with a head 1:2 'and securingnut 13. One'of-thefsections isfprovided 'withb'olt lholes 14 for the bolts, "and lano-ther section'is fashioned withoutwardly projecting bosses 1,5 ystamped from the metal and provided with -keyholelzsl-ots forv the' bolts. 'Tofprotecti the .bofltf heads and shield the slotted bosses 'caps 16 fare secured overthese partsas clearly :seen in :Bigsliand andthese kcaps kformi.pockets rio around the heads and bosses to prevent entrance of dust or dirt to the slotted bosses. The two sections oit' the disk wheel may be placed in proper initial position by first alining the holes 14e and slots 15'; the bolts are then passed through the. slots and holes and the nuts turned into comparatively loose engagement. Then the two sections are turned relatively in a circular or circumferential direct-ion until they are properly adjusted whereupon the bolts are tightened for securely clamping the sections together.

This turning action may be accomplished by the use of a suitable eccentric tool which is applied to a socket or opening A in one of the sections and adapted to coact with an eccentric and larger opening B in another of the sections as indicated in Fig. 1. A valve stem opening is also indicated at C and a pocket D is located between the sections within the rim /1 to accommodate the pneumatic valve of the tire, as usual.

At the hub portion of the wheel a simple but very eliective structure is provided for placing the sections of the disk wheel under tension and securely joining the sections with the hub members, as best seen in Figure 3. At the center of each of the sections 1 and 2 is provided an opening surrounded by complementary annular flanges 17 and 18 which form conical hub rings within which are located the transversely extending bearing'sleeve 19 for the journal end of the wheel shaft or axle. At the inner side ot the wheel this sleeve is fashioned with an enlarged head 2O having an exterior conical seat 21 for the conical hub ring 18, and the head is fashioned with an attaching flange 22 for connection with. parts not shown here in. To rigidly secure the conical hub ring 18 to the conical seat 21 and flange 22 the latter is provided on its inner il'ac-e with a series of radiating grooves 23 and the sec-4 tion 2 of the wheel is fashioned with a complementary series of crimps or ribs 24 stamped from the metal and fitting closely in the grooves 23 in order that the section 2 and the sleeve 19 may revolve together as a unit.

The bearing sleeve of the hub carries a. hub barrel 25 having at its ends complementary conical seats 26 and 27 the former frictionally engaging the conical hub ring 18 to hold it to its seat 21.- At the outer side of the wheel a hub flange 28 is itted over the bearing sleeve 19 and fashioned with a central open boss 29 in the form of a cone and it will be apparent that the hub ring 17 is clamped between this boss and the seat 27 of the barrel 25. rllhe bearing sleeve and outer hub flange are `keyed together is at 30.

The outer hub flange is secured to the section 1 in the saine manner that section 2 is fixed to the iiange 22, radial grooves 31 being provided in the inne-r :tace of the flange and complementary exterior ribs or crimps 32 being stamped in the metal of section 1 as shown in Fig. 3.

The whole of the hub structure is retained by means of the hub cap or nut 33 threaded on the eziteriorly threaded end of the bearingsleeve 19 at the outer side of the wheel, and the cap o-r nut is retained in locked position by means or" a pawl 34 pivoted in the cap and adapted to selectively engage notches or indentations 35 in the outer tace of the hub lange 28. f

It will be apparent that by turning home the cap, the wheel is drawn to proper` position and the hub rings 17 and 18 of the wheel sections are securely clamped between the barrell 25 and the hub lianges at opposite sides of the wheel. This action of the nut or cap also draws or pulls radially on-the sections toward the hub structure, thus placing the sections under the required tension to form a stable, well braced and durable lwheel structure. Y

Having thus fully described my invention, what. I claim as new and desire to secure by Let-ters Patent is- 1. In a disk wheel the combination with two disk sections and clamping means therefor of an integral oppositely extending lateral flange at the periphery of each section, said flange-s each having doubled portions forming outwardly lia-ring tire-retaining flanges, one of said tire-retaining ianges terminating in an inner lateral flange and the other tire-retaining fia-nge terminating in an exterior lateral flange. ,f

2. The combination in a disk wheel of a pair of relatively movable complementary Sections having overlapping langes forming a. rim structure, a boss formed in one section having' a keyhole slot and a complementary bolt hole in the other section, a` clamping bolt having a head and nut, and a cap fixed over said head and boss.

3. In a disk wheel the combination with a pair of sections each having a central opening and oppositely disposed conical hubrings, of a complementary hub-barrel between said rings, a bearing sleeve within the barrel and an inner hub flange on said sleeve, an outer hub flange keyed to the sleeve, and a hub-cap threaded on the sleeve.

4. In a. disk wheel the combination with a pair of sections each having an open conical hub-ring and a hub barrel between said rings, of a bearing sleeve within the barrel and an inner hub-fiange on saidV sleeve, an outer hub-flange, each said flanges having a series ot radial grooves and complementary ribs in the two sections, and a hub cap threaded on the sleeve.

5'. In a disk'wheel the combination with a pair of sections having central openings and opposed conical hub-rings and a coinplenientary hub barrel therebetween, of a. bearing sleeve Within the barrel and outer and inner hub flanges, means for securing each llange to a Section, and means for clamping said anges, hub rings and barrel on the bearing sleeve.

6. In a disk Wheel the combination with a. pair of sections having central openings l0 and opposed conical hub rings, and a` hub barrel having at its ends complementary conical seats for said rings, oi a hearing sleeve Within the barrel having an integral nulo fizing'e and grooves therein, a complementary hub flange keyed to Said sleeve and provided with grooves, each said section having ribs complementary to said grooves, and a threaded cap on said bearing sleeve.

In testimony whereof I aix my signature.

WILLIAM o. LEONARD.
